Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment Low-dose CT, Motion Analysis, T1Rho MRI for shoulder osteoarthritis?

Research shows that low-dose CT scans can effectively provide detailed images for diagnosing shoulder issues and planning surgeries, while MRI techniques like T1Rho can offer valuable insights into cartilage health, which is important for understanding osteoarthritis.12345

Is it safe to use diagnostic imaging techniques like Low-dose CT and T1Rho MRI for shoulder osteoarthritis?

Research shows that low-dose CT scans, including those with metal artifact reduction, are generally safe and have been used in various studies for shoulder imaging. T1Rho MRI has been tested in pilot studies and is considered safe for assessing shoulder joint health.12678

How is the imaging treatment for shoulder osteoarthritis different from other treatments?

This treatment uses advanced imaging techniques like 3D MRI and ultra-low-dose CT scans to create detailed models of the shoulder, which can help in diagnosing and planning treatment for osteoarthritis. Unlike traditional methods, these techniques offer a non-invasive way to visualize the joint in three dimensions, potentially improving accuracy in diagnosis and surgical planning.12379

What is the purpose of this trial?

Osteoarthritis (OA) is a progressive disease resulting from the degradation of synovial joint articular cartilage over time.The hallmark symptom is diffuse aching and progressive pain made worse with activity. Loss of range of motion and compromised function inevitably follow. This degenerative disease can affect the shoulder joint. When symptoms become refractory to conservative treatment such as anti-inflammatory medication, steroid injections, activity modification or physical therapy; surgery (total or reverse shoulder arthroplasty) may be considered.Idiopathic shoulder OA is typically characterized by posterior subluxation of the humeral head upon the glenoid and posterior bone loss. An imbalance in the application of forces applied to the proximal humerus by the posterior and anterior rotator cuff muscles has been postulated to be the leading cause of idiopathic shoulder OA. However, there is only preliminary evidence to support this theory and the etiology of this pattern of deformity is unknown. The theory the posterior humeral head subluxation is a precursor to OA is only supported by very low-level evidence and no longitudinal studies have been conducted. As a result, the cause and natural history of shoulder OA remains unknown.Research into this area is urgently needed to generate knowledge that will inform future treatments aimed at modifying and slowing the progression of shoulder OA and to reduce the need for shoulder replacement therapy.The aim of this project is to develop an understanding of the pathophysiology of shoulder OA.
